showing the parts at the. end of the first movement performed in' unlocking the coupler; Figs. 3 and 4 are similar views showing the parts respectively in loekset position and when the knuckle is thrown completely open; Fig. 5 is a side elevation, partly in. section showing the lock `in full outline;

Fig. 6 is a side elevation showinr the working parts of the coupler in dotted` lines; Fig. 7 is a plan View, partly 1n section showing two of my couplers coupled together; Fig. 8 is a perspective View showing the iitting of the shuttle with the bottom of the lock; Fig. 9 is a horizontal section through the lower part of` the coupler-head on theline lX-IX of Fig. 17 the operating parts of the coupler being omitted; Figs. 10 and 11 are det-ail views of the knuckle; Figs. 12 and 13 are detail views of the shuttle; Fig. 14 is a perspective view of the lock.

In the drawing 2 is the coupler head, 3 the knuckle, having a` flat locking face 3 inclined to the longitudinal center line of the coupler and having a hook-Shape tail 3 which extends within a hole 2 in the side wall ot' the coupler-head, and by bearing upon the couplerhead relieves the pivotpin B from strains and holds the knuckle in place in case of breaking of the pivot-pin. The knuckle has a locksetting ledge 3 below the hooked ortion 8a of the tail and separated therefrom by a recess 3h.

l'llhe lock 4 has on the knuckleside of its upper portion a ledere Ll which supports the lock on the knuck e when the knuckle is locked. The lock has at its 'base a hooked portion et and at the middle a recess 4J which, when thelock is raised to unlocked position, allows the knuckle to swing open.

5 is a shuttle, shown clearly in Fig. 8. It has three functions. lt retains the lock in locked position; holds it in locked position; and is the member by which the knuckle is directly thrown open. At thezup er portion of the shuttle is a hook-shape proj ect1on 5 ada ted to engave a seat upon the locksettino edge 3 of Jdie knuckle, and a rear shoulder 5? which when the parts are in locked position as shown in Fig. 1 moves by gravity under the shoulder 2a of the coupler-head and revents accidental upward creeping of t e lock andshuttle during the jarrinv motion of the car. The shuttle has at its bottom portion trunnions 5 and 51. The trunnion 5 slides within a groove 2b (Figs. 5 and 9) in the couplerhead and the trunnion 5d slides within a' guide-way 2 (Figs. 1 and 9) between ribs 2 and 2 ou the couplerliead.` rllh'e shuttle also has a middle 4trunnion 5e out of linev from the trunnions 5" and 5d which fits within a hooked portion 4 at the bottom of the lock 4. The shuttle also has an elongated hole 5 at the rear'of its bottom portion into'which the hooked end 7 of a litting link 7 tits thus positively articulating the f lifting link' with the shuttle. This link is pivoted ata to a lever 6 which is pivotally attached at 6 to the bottom ear of the coupler-head and has an eye 6a for the reception of the uncoupling rod 8.

When the parts are in locked position the lock is supported on the knuckle tail by the y fitting oi the' ledge 4.- ou top of theloek as shown in Fi i'. l, and the shuttle being then supported within the hooked portion 4; `of the lock by the truiuiion 5e which is forward of the center of gravity of the shuttle, the shuttle will drop backward by gravity, as shown iii Fig. l, so that its shoulder 5l will rest bei'ieath lthe shoulder 2 ori-the couplerhead and will thus prevent upward creep* ing as above described.

iVlien it is desired to unlock the coupler the uiicoupling rod is raised, thus lifting the lever and causing the hooked end 7 of the link 7 to move upwardly within the hole 5 ofthe shuttle and to turn the shuttle on the truiuiioii 5 within the lock, causing the shoulder?)b to nieve out from beneath the stop shoulder 2 as shown in` Fig. 2. This forward niotionof the shuttle is liniited in extent by the rib 2e with which the forward surface of the shuttle 5g engages, and this engagement continuesfuntil the projection 5a at the top of the shuttle has passed behind and opposite to the-knuckle tail. Then as the shuttle is raised far enough-to clear the rib 2e, the projection 5a on the shuttle moves for-v wardly on to the ledge 3 of the knuckle tail and engages therewith thus holding the shuttle and therebysupportin'g the lock in lockset position,vin which position the recess 4b is opposite the knuckle tail, thus leaving the knuckle-tail free to open when'it is pulled -by the motion of an adjoining car. The parts are thus brou ht into lockset positiontrunnions 5 and 5d after these trunnions, have engaged the top of the groove 2j and the curved top of the rib 2e respectively. The upper portion of the shuttle 5a then will engage the rear of the knuckle tail and will force the knuckle open. This action is shown in Fig. 4. Fig. 5 shows the groove 2b with the trunnion 5 slidin within it and the trunnion 5e in section within the hooked portion 4a of the lock.

It will be noticed, among other points of novelty and ladvantages of my device, that the trunnion 5 of the shuttle 5 is not in line with the trunnions 5 and 5d which vengage the coupler head, but the trunnion 5e 1s so placed relatively to the position of the hook 7 of the link 7 within the hole 5 that dur-- ing the initial lifting of the lock prior to the locksetting position this trunnion is almost directly above the position of the hook. There is,d therefore, very little tendency of the lifting link to tip the shuttle until the trunnions 5 and 5d have engaged the top of the slot 2b and the top of the rib 2 on the coupler-head, so that friction between the shuttle and the wall of the coupler-head is avoided and the part-s are rendered easy to move.

Another feature of novelty of the device resides in the formationof the shuttle with a hole 5 for engagementwvith the end of the lifting link 7. The presence of this hole enables the lifting link to be connected with the shuttle by a mere hook 7, and the flexible connection of these parts renders it unnecessary to take special pains to hold the other end of the uncoupling link of this lifting lever'in precise position.

When the .rod 8 is released after the knuckle has been thrown open or pulled open from lockset position, the shuttle 5 will drop back by gravity `out o f the path of the knucklev tail so that when theknuckle` -tail next closes itmaynot strike theo shuttle.

The head of theflock 4 above the recess 4b rests upon the top of the knuckle tailwhile the knuckle is open, and as soon as the knuckle tail is closed the lock will drop by rear of/"the coupler-head gravity into locking position and the shuttle will resume its lock-retaining position beneath the shoulder 2 as shown 1n Fig. 1.

During the vertical lnotion of the lock its rear portion is guided by the rib 2f at the and is thus prevented from moving back far enoughto disengage its hooked portion from the shuttle.

The trunnion 5l of the shuttle is accessible' from the outside of the coupler-,head through the lateral slot 2g (Fig. 6) This enables the lock to be tripped from lockset position without opening the knuckle, by an u ward ush from a mans iin er or the end o a rod inserted through the s ot 2g below the trunnion 5d. This will lift'I the rojection 5nl from its seat onthe ledge 3 o the knuckle and the shuttle being free to swing backward by gravity the lock will then drop into the locking position shown in Fig.. l.

In my former patent, No. 833,434, the tripping of the device was effected by enlargln the hole in the side of the couplerhead t rough which the end of the knuckle tail projected, so that a rod could be inserted through this hole. This, however, was not so desirable as the present construction, for it was more dii'cult to release the parts and the enlar ement of the hole was somewhat undesirab e in point of View of strength. In 95 the resent construction the slot 2g being at the bottom portion of the coupler-head be- ,low the trunnion of the shuttle when in lockset position does not weaken the coupler substantially, and it makes the trippingeasy.

The advantages of m invention will be appreciated by those skilled in the art. It strengthens the construction of the cou ler, makes it more efiicient in action, and is ot erwise very desirable.

I claim as my invention:

1. A coupler having a swinging knuckle, a vertically moving lock, a shuttle connected with the lock having a rearward tilting motion to engage the cou ler-head and having a forward motion for ocksettingand opening the knuckle and having a projectin portion whichv successively 1n its forwar motion engages a locksetting portion on the knuckle and then pushes the knuckle open, and a-lifting link positively articulated with the shuttle.

2. A coupler having a knuckle, a lock, a shuttlepivotally connected with the lock and ada ted to throw the knuckle open, a liftin hnk for the shuttle, the connection of sa1d lifting -link to the shuttle and the ivotal connection of the shuttle and lock being so related that the one is substantiall above the other when .the parts are lifte and means whereby the continued lifting of the shuttle will cause it to tip.

3. A couplerhaving a lock, a shuttle connected with the lock having a trunnion 5 for engagement with the ock and other .1.30
